All 36 metropolitan boroughs, 23 out of 50 unitary authorities, 78 out of 238 English districts, all 22 Welsh principal councils, and 1 directly elected mayor
The Labour Party finished in 3rd place by vote share, trailing the Conservatives by 20%, the largest such margin ever between the two main parties. Aside from the strong showing for David Cameron's Conservatives, Plaid Cymru and the Lib Dems each made net gains of over 30 seats and the BNP made 10 net gains to finish with over 30 seats.
The strong showing for the Conservatives and the disappointing showing by Labour reflected the change in the political mood of Britain at the time, where the Labour government, now led by prime minister Gordon Brown, had suffered a slump in popularity due to the financial crisis and economic fears which were affecting Britain at the time.
